Do you have a PEA providing ecological evidence for Cornwall planners at validation?
We provide the baseline ecological evidence used by Cornwall LPAs to validate applications and confirm whether further protected species surveys are required.

We stay with you from first call through to submission.
Preliminary Ecological Appraisal (PEA) is typically needed for Cornwall projects where works involve vegetation clearance, demolition, boundary changes, ground disturbance, or features such as former industrial land, field margins, watercourses or mature trees. This includes small residential projects and larger commercial schemes. It gives the council the information they need to decide whether protected species are affected and what, if anything, must be done next.
By identifying risks early, a PEA helps clarify whether ecology could affect your project and what further surveys may be needed to keep it moving on schedule.
Across Cornwall, particular environments frequently prompt PEA requirements:
• Coastal cliffs and coves from St Ives to Newquay — maritime vegetation and sheltered pockets raise bird and bat sensitivity
• Cornish hedges and valley bottoms across Bodmin and the Roseland — linear habitat networks link amphibian and mammal movement
• Mining heritage land around Camborne, Redruth and St Just — spoil, shafts and disused structures often support reptiles and invertebrates
• Historic harbours and granite villages like Fowey and Mousehole — traditional roofs and mature gardens indicate strong bat potential
Clarity at concept stage prevents reactive mitigation later.
Our PEA services cover every Local Planning Authority in Cornwall, delivering robust ecological baselines to help applications move efficiently from submission to determination.
Cornwall planning authorities are required to apply the Wildlife & Countryside Act 1981, the Habitats Regulations and the NERC Act 2006 when determining applications. A PEA is the primary evidence they use to confirm ecological risk has been identified proportionately.
Without a clear PEA, applications can be held at validation, delayed by seasonal survey requirements, or receive conditions only after further ecological evidence is provided.
We carry out Preliminary Ecological Appraisals (PEAs) year-round across Cornwall. Follow-up species surveys are seasonal; however, a PEA indicates if any are needed, allowing your project to keep moving without unnecessary delays.
Our PEA aligns with Cornwall LPA evidence expectations and provides:
A complete habitat baseline and ecological constraint map
Protected-species risk screening with clear survey guidance
Seasonal timing advice to keep your project on schedule
A planning-ready PEA report for LPA validation
The result: confident ecological decisions and a smoother planning process.
Boundary and proposed works checked against policy and planning context.
On-site ecological walkover using DEFRA-aligned UKHab methods.

A Preliminary Ecological Appraisal (PEA) is an initial ecological survey used to assess habitats, biodiversity value, and the potential for protected species on a site in Cornwall. It helps identify ecological constraints early in the planning process.
A PEA is typically required where development in Cornwall may affect habitats such as coastal areas, grassland, heathland, woodland, or buildings that could support protected species.
Cornwall’s coastline, cliffs, and marine influenced habitats can increase ecological sensitivity. These environments often support protected species and designated sites, making PEAs an important part of planning.
Habitats commonly assessed include coastal cliffs, heathland, grassland, woodland, wetlands, hedgerows, and developed land, all of which may support protected species.
A PEA survey involves a site walkover and a desk study review of ecological data. It evaluates habitat types, ecological features, and the potential presence of protected species.
Yes, developments near the coast in Cornwall are more likely to require a PEA due to the ecological importance of coastal habitats and the presence of protected species.
Yes, a PEA identifies ecological constraints early, allowing developers to address issues before submission and reducing the risk of delays or additional requirements.
If further surveys are required, they will focus on specific protected species and may need to be carried out at certain times of the year depending on survey requirements.
A PEA provides baseline ecological information that supports Biodiversity Net Gain assessments. It helps identify habitat value and informs biodiversity enhancement strategies.
Cornwall Council is the main Local Planning Authority for the region and may require PEAs where relevant. You can review planning requirements via Cornwall Council’s planning portal: https://www.cornwall.gov.uk/planning-and-building-control/.
